Jeremy KerrandGreg Kroah-Hartman a37f6d5541 mctp: serial: Fix starting value for frame check sequence ...

[ Upstream commit 2856a62762 ]

RFC1662 defines the start state for the crc16 FCS to be 0xffff, but
we're currently starting at zero.

This change uses the correct start state. We're only early in the
adoption for the serial binding, so there aren't yet any other users to
interface to.
